MOTION-TRANSMITTING DEVICE.

Specification of Letters Patent.

Patented Sept. 13, 1910.

Application filed January 29, 1919. Serial No. 540,886.

To all whom it may concern:

Be it known that I, I)AVID E. SnLnnns, a citizen of the United States,residing at Van Orin, in the county of Bureau and State of Illinois,have invented new and useful Improvements in Motion-TransmittingDevices, of which the following is a specification.

My present invention relates to means for transmitting rotary motion todevices to be rotated; and it consists in the peculiarand advantageousdevice hereinafter described and definitely claimed.

In the drawings, accompanying and forming part of this specification:Figure 1 is a perspective view of my novel device. Fig. 2 is an enlargeddetail view, partly in elevation and partly in section, illustrative ofthe manner in which the belt-shifting lever is connected with thebracket by which said lever is carried.

Similar letters designate corresponding parts in both views of thedrawings, referring to which:

A is the lower member of the main frame comprised in my novel device,and B is the upper member of said frame. The lower member A comprises abase plate a having apertures b for the passage of screws (not shown) bywhich it may be fixedly connected to a floor, and a central upright c,of circular form in cross-section, fixed to and rising from the base.The upper member B comprises standards (Z on which are alined journalboxes 6, and a vertically-disposed depending sleeve 7", of circular formin cross-section, integral with said standards. The said sleeve f of themember B is designed to receive the upright 0 of member A, as shown, andis also designed to be turned and adjusted vertically on said upright 0so as to properly position the shaft, hereinafter described, forconnection to the shaft or trunnion of the device to be rotated. One ormore preferably two) screws 9 are carried by the sleeve f and these areadapted to be set against the upright c with a view of adjustably fixingthe frame member B with respect to the member A.

Journaled in the boxes 6 of the frame member B is a shaft C, and mountedon said shaft at one side of the member are fast and loose pulleys D andE, designed for the connection of a band (not shown) leading from asuitable source of power. At the opposite side of the member B, withreference to the pulleys D and E, the shaft C is provided with a.universal joint F, the outer section it of which is provided with asocket 2', of angular form in cross-section, designed to receive theangular end on the shaft or trunnion of the device to be rotated.

G is a bracket having a stem j that is screwed or otherwise fixed to theframe member 13, and also having a resilient or springy and aperturedloop 7c, and II is a belt-shifting lever having at its outer end a loopI to receive the belt (not shown). At its inner end the lever H isprovided with an angular stem m, and the said stem is journaled in theapertures in the opposite portions of the bracket loop is and isthreaded adjacent its end to receive a nut a. By turning the said nut upon the stem m the loop 70 is put under tension, and consequently saidloop serves, by tending to resume its normal state, to exert pressureagainst the nut, and in that way prevents casual swinging of the leverII without in terfering with the manual swinging of the lever necessaryto shift the belt from the fast pulley to the loose pulley and viceve'rsa. From this it follows that when the lever is swung to shift thebelt from one pulley to the other, there is no liability of the beltaccidentally moving back to the first-named pulley.

My novel device is designed more particularly for transmitting motion tothe rotary body of a churn located alongside the device, and when thesquare end of one of the trunnions on the churn body is placed in thesocket 2' of the universal joint F, and the shaft C is rotated, it willbe understood that the churn body will also be rotated. It

will also be understood that my novel device is calculated to hold thechurn perfectly steady and hence there is no necessity of fastening theframe of the latter to the floor. It will further be gathered from theforegoing that my novel device is adjustable to churns and other devicesof various heights; that it permits of the churn or other device to beactuated being set at an angle; and that when it is used, the connectedchurn or other device may be started or stopped slowly, as occasiondemands.

\Vhile I have shown the bracket G and lever II for use in connectionwith a belt extending horizontally from the pulleys D and E, I wouldhave it understood that the said bracket may be fi xed in a position ata i right angle-to the position shown in Fig. 1, in which event thelever H would be disposed upright to cooperate with a belt extendingvertically from the pulleysi. 6., from the pulleys to an overhead shaft.

The construction herein illustrated and described constitutes the bestpractical embodiment of my invention that I have as yet clevised, but itis obvious that in the future practice of the invention such changes ormodifications may be made as do not involve departure from the spirit ofthe invention as claimed.

Having described my invention, what I claim and desire to secure byLetters-Patent, is:

A device for the purpose described, comprising a lower frame-memberhaving a base plate and an upright, of circular form in cross-section,on the base plate, an upper frame-member having a sleeveadjustablevertically and adapted to turn on the up: right of the lowermember, means for adjustably fixing the sleeve of the upper member tothe upright of the lower member, a shaft journaled in the upper framemember, fast and loose pulleys on said shaft, a universal joint on theshaft at one end thereof, a bracket fixed to the upper frame member andhaving a resilient loop, a belt-shifting lever having an angular stemjournaled in the opposite portions of said loop, and a nut threaded onsaid stem and bearing against one of the said portions of the re silientloop. 7

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
